March exhibition (13)
(Other definitions for parade that I've seen before include "Row of shops, march" , "Exhibit" , "Air - display" , "March-past of troops etc." , "Easter ___ , 1948 film with Judy Garland and Fred Astaire" .)
I believe this is a double definition.
'march' is the first definition.
(as in a political demonstration)
'exhibition' is the second definition.

(Other definitions for demonstration that I've seen before include "It's to voice protest" , "Protest march/meeting" , "March; proof" , "Exhibition, protest" , "Protest march" .)
